How did the travels
of Marco Polo affect
Europeans?

Europe was not the only one that positively affected by Marco Polo's travels. Unsurprisingly, China, too, was affected in a positive manner. Marco Polo had introduced gunpowder to the Chinese. With trade between Europe and China, the Europeans were introduced to citrus fruits, spices, and other newly seen goods.
